Nick Kyrgios received a warning for unsportsmanlike behaviour after a running argument with the umpire while twice serving under-arm.

Australian Nick Kyrgios lost to third seeded Rafael Nadal 3-6, 6-3, 7-6, 7-6 in the second round of Wimbledon 2019 on Thursday. The match had its moments, with unseeded Nick Kyrgios finding himself in the firing line for an unsportsmanlike behaviour after running into an argument with the umpire while twice serving under-arm. The serve left his Spanish opponent Rafael Nadal and the London crowd surprised. It was also the first meeting between Rafael Nadal and Nick Kyrgios on the tennis court, after the former had blasted the latter for lacking respect "for the public, the opponent and himself" at the Mexico Open.
